A model for hysteresis in mechanics using local minimizers of Young measures
نویسنده
چکیده
A model for effects related to hysteresis in continuum mechanics is introduced. Its key idea is to consider local minimizers of Young measures describing the deformation gradient of a body. These Young measures are defined as limit of a quasi-static evolution by means of a gradient flow with respect to a special “regularized” Wasserstein metric. The model is described for the space-homogenous case, and some one-dimensional examples show the occurence of hysteresis and illustrate possible applications to fracture.

Modeling SMA actuated systems based on Bouc-Wen hysteresis model and feed-forward neural network
Despite the fact that shape-memory alloy (SMA) has several mechanical advantages as it continues being used as an actuator in engineering applications, using it still remains as a challenge since it shows both non-linear and hysteretic behavior. To improve the efficiency of SMA application, it is required to do research not only on modeling it, but also on control hysteresis behavior of these m...
متن کاملYoung measure flow as a model for damage
Models for hysteresis in continuum mechanics are studied that rely on a time-discretised quasi-static evolution of Young measures akin to a gradient flow. The main feature of this approach is that it allows for local, rather than global minimisation. In particular, the case of a non-coercive elastic energy density of Lennard-Jones type is investigated. The approach is used to describe the forma...

In this paper, hysteretic behavior modeling, system identification and control of a mechanism that is actuated by shape memory alloy (SMA) wires are presented. The mechanism consists of two airfoil plates and the rotation angle between these plates can be changed by SMA wire actuators. This mechanism is used to identify the unknown parameters of a hysteresis model. Prandtl–Ishlinskii method is ...

We review recent theories of non-classical, structured deformations and integral representations for their Helmholtz free energy. Energy minimizers for a body undergoing shearing at two di¤erent length scales and for a bar experiencing both smooth extension and macroscopic fractures then are determined, and applications to the shearing of single crystals and to the cohesive fracture of solids a...
متن کاملThe effects of the violation of local independence assumption on the person measures under the Rasch model
Local independence of test items is an assumption in all Item Response Theory (IRT) models. That is, the items in a test should not be related to each other. Sharing a common passage, which is prevalent in reading comprehension tests, cloze tests and C-Tests, can be a potential source of local item dependence (LID). It is argued in the literature that LID results in biased parameter estimation ...
